PLAYBOY boss Hugh Hefner has tied the knot for the third time – with a blonde playmate 60 years his junior who jilted him 18 months ago.

The 86-year-old married Crystal Harris, 26, in a low-key ceremony at his Playboy Mansion on New Year’s Eve.

Glamour model Harris, who was raised in the US by her British parents, revealed on Twitter that she had become the multi-millionaire’s wife.

She changed her name to Crystal Hefner before writing: “Today is the day I become Mrs Hugh Hefner. Feeling very happy, lucky, and blessed.”

Her delight stands in marked contrast to the last time the pair were due to wed in July 2011.

On that occasion she had a change of heart just five days before the ceremony and auctioned off her £55,000 diamond engagement ring.

Unlike previous plans for a lavish wedding bash with hundreds of guests, the couple appear to have opted for a more modest affair this time with his brother Keith as best man.

Pictures posted online by the model showed a room inside the magnate’s Los Angeles home lined with just two dozen chairs.

Another photo, entitled “Mr and Mrs Hugh Hefner”, showed the couple posing under an arch of pink and white flowers.

Hefner was initially silent about the ceremony but went public yesterday with an online message saying: “Crystal and I married on New Year’s Eve in the mansion with Keith as my best man. Love that girl.”

He later posted a picture of himself wearing a dressing gown and sailor hat cosying up to his new wife dressed in a “pale pink mermaid dress”.

They met at Hefner’s annual Halloween party in 2008. She moved in with him a few weeks later and was Playboy Playmate of the Month in December 2009.

Hefner, a father of four, has been hitched twice before.

His first marriage to Mildred Williams ended in divorce in 1959 after 10 years. He wed Kimberley Conrad, also a former Playmate, in 1989 but they divorced in 2010.
